Abstract: 610,320. Aerials. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. April 27, 1945, No. 10731. Convention date, April 29, 1944. [Class 40 (vii)] A device for focussing U.H.F. electromagnetic energy is formed of two wave-guiding parts consisting either of two sheets of dielectric material or two pairs of conductive sheets between which the energy passes, the two wave-guiding parts having corresponding edges defined by different geometrical characteristics and being united along these edges to form a single wave-guiding member having a collecting (or radiating) aperture at one end and a focal region at the opposite end. In one form, Figs. 1, 2, sheets 1, 3 of material having low transmission loss, e.g. polystyrene, are shaped so that sheet 1 has circular edges and sheet 3 is of trapezoidal form. The sheet 3 is bent and its edge 7 united with the corresponding edge 5 of the sheet 1 to form the device illustrated in Fig. 2. The surfaces of the sheets 1, 3 may be coated with conductive material. In Figs. 3, 4 (not shown), the component sheets before joining have circular edges, one of which has twice the radius of the other. The arrangement in both forms of construction is such that the device has a linear aperture 11 at one end and serves to focus at the other end energy in the form of a plane wave polarised to pass into this aperture. A third sheet or pair of sheets may be added to sheet 3 to form a structure as shown in Fig. 6 with the centre sheet bent so that the outer sections lie in parallel planes and are directed in the same or opposite directions. In another construction utilizing three sheets or pairs of sheets, the outer sheets are circular, Fig. 8 (not shown). In a further construction, utilizing sheets 55, 57 shaped as in Fig. 9, part of the semicircular sheet 57 is bent round the surface of a cone so as to form an annular focussing region 53 at the base of the cone, Fig. 10. A reflecting surface may be provided along the edge 77-79 of sheet 57 or a lens may be arranged near the edge 61. A -rotating wave-guide arm 71 may be arranged to scan the focal region 53. Specification 610,318 is referred to.

Filed: 1918-06-29
Abstract: 161,592. Josse, E., and Gensecke, W. June 29, 1918. Water, distilling.-In apparatus in which " makeup " feed-water for a steam turbine or other condensing engine is distilled by means of the exhaust steam the distilled water is condensed in a condenser which is kept at a lower temperature and a higher vacuum than the main condenser. In the arrangement shown in Fig. 1, a branch from the exhaust pipe c conveys steam through a surface evaporator e communicating with a conductor l through which the cooling-water, or a part thereof, passes on its way to the main condenser d. Separate pipes and pumps o, p are provided for withdrawing air and condensate from the condenser l, or the air and water may be passed to the main condenser d, which is placed at a lower level than the condenser l to allow of the requisite difference of vacuum being maintained. In a modification, the surface condenser l is replaced by a jet or like condenser and two separate bodies of cooling- water are employed. In the arrangement shown in Fig. 4, a portion of the cooling-water from the main condenser d is utilized as the make-up water, passing into the chamber e and being there evaporated by the heat which it has received in the condenser d, the necessary vacuum being maintained, as before, by a condenser l. In this case the whole of the cooling water passes through the condenser l. The evaporation in the chamber e may be assisted by a jacket 7 heated by a portion of the exhaust steam.

Title: Viscosity indicating instruments
IPC: G01N11/08
Filed: 1930-04-08
Abstract: 356,721. Testing viscosity of liquids. MAPEL, L. A., 416, North 3rd Street, St. Louis, Missouri, U.S.A. April 8, 1930, No. 11194. [Class 106 (ii).] Relates to apparatus for continuously indicating the varying viscosity condition of a lubricant flowing under pressure in a circuit for the continuous lubrication of mechanism in which a gauge is connected in the circuit or in a branch thereof to receive continuously the pressure of the circuit and thus indicate the viscosity of the lubricant and consists in connecting a regulator to impose a substantially constant pressure on the circuit in advance of the viscosity indicating device. The invention is described as applied to the lubricating system of a motor vehicle. A base 9 is screwed to the crank-case 11. An inlet passage 12 communicates with the pipe system through a fitting 13 and also communicates with a downward passage 14 having a restriction 15 closed by a ball valve 16. A spring 17 which may be adjusted by a screw 18 acts on the ball and is housed in the tubular end 19 of the extension 10. Slots 21 permit discharge. Threaded into the upper end of the passage 14 is a stem 22 having in the lower end an axial bore 23 with outlet passages 24. An orifice plug 25 is screwed into the bore, the approaches to the orifice being flared on either side. A cup casing 29 is soldered to the head 28 the lower edge being rolled to engage a gasket in an annular depression in the base 9. A bore 32 at the upper part of the stem 22 communicates through a fitting 34 with a pressure pipe 35 leading to a pressure gauge. The body 9 has an outlet passage 37 connected to a pipe 38 leading to the crank case and containing a wire 41 bent to an irregular shape to furnish an obstruction. The oil from the pipe system after passing through a filter passes into the passage 12 and through the orifice 27 the relief valve 16 keeping the pressure in the duct 14 constant. The oil flows quietly out of the passages 24 into the casing 29 and runs out through the pipe 38. The air in the chamber 29 is under a pressure impressed upon it by the counterpressure set up by the resistance tube 38, and the pressure is indicated on the gauge which is provided with a scale indicating " low," " normal " and " high " viscosities. As pressure of oil lubricating systems vary according to make of vehicle, means such as constrictions must be introduced if necessary to bring the pressure down to a value suitable for the viscosity indicating device. The oil circulating in the system carries along with it bubbles of air which are given up when the pressure is suddenly reduced as when the orifice 25 is passed. The air in the chamber 29 is thus replenished to some extent from this source. Also when the apparatus is not being used the oil returns to the crank-case and during cooling of the device some fresh air is sucked in through the pipe 38 and through the valve 16 which does not fit tightly.
